I think the reason you are in a loop is at the Print Center you are likely choosing to print the wrong tax year. It sounds like you are choosing to print/save/view the prior year return, which would "seem" right, but is actually wrong. That's the wrong choice and will only result in a loop like you are experiencing, and it takes you back to the Tax Home page. Instead, you have to choose to Print/save/view THIS YEAR'S return in order to get the payment screen (see explanation below).
NOTE: Before paying, make sure the 2017 and 2018 returns are in the same account.
Since you say you have already upgraded to PLUS, open the return again and in the left menu column click on TAX TOOLS, then choose to go back to the Print Center again.
- At the Print Center you have to choose to "Print, save, view THIS YEAR's return." (yes, you say "this year's" because you are paying for PLUS 2018 to unlock the prior returns.) You don't really have to print it.
- Then on the next screen choose to PAY NOW. (for this unlocking purpose, you cannot use the "Pay Later" feature if it's offered.)
- The next screen will be an Order Summary. It should show PLUS for 19.99.
- Next screen says "Pay with Credit Card", but it can also be a debit card or prepaid debit card.
NOTE: Remember all PDF tax documents and data
files are very sensitive files, since they contain your personal ID
info, financial data, and possibly bank account numbers, etc. Be sure
to store them safely and securely to guard against computer theft,
hacking, etc.
